难以理解为什么不更新变量

我是一个新手程序员，我很难理解为什么这个不工作。我有一个"ConnectedClientList"类:

public class ConnectedClientList
{
    static readonly object _lock = new object();
    public static IList<ClientPeer> ConnectedClientPeers;
    static ConnectedClientList()
    {
         ConnectedClientPeers = new List<ClientPeer>();
    }

    public static IList<ClientPeer> GetClientPeers()
    {
        lock (_lock)
        {
            return ConnectedClientPeers;
        }
    }
    public static void AddClientPeerToConnectedList(ClientPeer client)
    {
        lock (_lock)
        {
            ConnectedClientPeers.Add(client);
        }                
    }
    public void RemoveClientPeerFromConnectedList(ClientPeer client)
    {
        ConnectedClientPeers.Remove(client);
    }
}

我在另一个类中有这个:

ClientPeer clientPeer = new ClientPeer(request, Logger, _clientHandlerRegistry);
ConnectedClientList.AddClientPeerToConnectedList(clientPeer);
Logger.InfoFormat("Added clientpeer to list. Count is now: {0}", ConnectedClientList.ConnectedClientPeers.Count);

最后是这个

public CharacterUpdateEventHandler(ILogger logger)
    {
        Logger = logger;
        IFiber testFiber = new ThreadFiber();
        testFiber.Start();
        testFiber.ScheduleOnInterval(SendUpdateEventToClients, 1000, 5000);
    }
    public void SendUpdateEventToClients()
    {
        if(ConnectedClientList.GetClientPeers() != null)
            Logger.InfoFormat("# of connected client peers: {0}", ConnectedClientList.GetClientPeers().Count);
        else
        {
            Logger.InfoFormat("ConnectedClientPeers is null");
        }
    }

我正在尝试使用Exitgame的Photon服务器构建服务器。当我第一次创建客户端，然后将其添加到"ConnectedClientPeers"，我立即有调试信息说，"ConnectedClientPeers"列表实际上现在有一个计数为1。

我正在运行的线程似乎正在重复"SendUpdateEventToClients"很好，但该函数中的调试消息总是说我的"ConnectedClientPeers"列表的计数为0。

我敢肯定这可能是一些我没有意识到的简单问题，但在过去的几天里，我没有找到任何解决方案。任何帮助或建议都是非常感激的。谢谢!

我更新了类，使整个类静态，但仍然有相同的问题。

public static class ConnectedClientList
{
    static readonly object _lock = new object();
    public static readonly IList<ClientPeer> ConnectedClientPeers;
    static ConnectedClientList()
    {
         ConnectedClientPeers = new List<ClientPeer>();
    }

    public static IList<ClientPeer> GetClientPeers()
    {
        lock (_lock)
        {
            return ConnectedClientPeers;
        }
    }
    public static void AddClientPeerToConnectedList(ClientPeer client)
    {
        lock (_lock)
        {
            ConnectedClientPeers.Add(client);
        }                
    }
    public static void RemoveClientPeerFromConnectedList(ClientPeer client)
    {
        ConnectedClientPeers.Remove(client);
    }
}
